Title: Improvements in or relating to electric proximity control systems
Inventor: ROUT FREDERICK PERCY
IPC: G05D9/12
Filed: 1955-12-16
Abstract: 822,900. Electric tests. GREEN & SILLEY WEIR Ltd., R. & H. Dec. 12, 1956 [Dec. 16, 1955], No. 36215/55. Class 37. [Also in Group XXXV] The level of a liquid is maintained between predetermined limits by means of a single capacitive probe, the effective value of which is changed at one of the predetermined levels so as to set the probe for controlling the other limit. As shown, the conducting probe 1 acts as a capacitance in one arm of a bridge fed with R.F. current. When the liquid reaches a predetermined high level the bridge is so far out of balance that relay 6 in the diagonal is operated. The relay inserts capacity 7 in parallel with the probe and switches on pump 15. Thus, as the level falls relay 6 remains operated until the low level is reached, when the bridge is insufficiently unbalanced to maintain the relay operated and it drops out, stopping pump 15. Capacity 13 may be switched in parallel with the probe by manually-operated switch 14 to simulate the arrival of the liquid at the higher level when it is actually at the lower. The bridge is then adjusted to ensure that the relay just operates.

Title: Improvements in or relating to signal evaluating equipment
IPC: G01S7/292
Filed: 1962-10-02
Abstract: 1,019,300. Pulse radar. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Oct. 2, 1962 [Oct. 18, 1961], No. 37428/62. Heading H4D. A circuit arrangement for computing digitalized received radar signal trains in which targets are represented by a series of binary ONES of various lengths, but at most of n positions in length comprises means for feeding a digitalized train of received radar signals, arranged according to range zones to the input of a multi-element shift network the outputs of the elements of which are fed, in order to determine the target centre, to a logic network so constructed that a ONE is present at it output only when a block of at most n ONES is located in the middle of the shift network or when the first (in time) ONE if a larger block resulting from two targets has reached a limiting unit provided within said network remote from the input end thereof or when the last (in time) ONE of said block has reached a limiting unit provided in said network near the input end thereof. As shown in Fig. 1, a shift network 1 has its input 2 fed with digitalized radar train and shifts it in sequence and in order of range zone, the network having at least n + 2 elements and n + 2 outputs represented by a single line. These outputs operate a device 3 for regenerating distorted pulse trains, these trains being fed to a device 4 for reduction of the ONE-block. The device 4 reduces each block such that the smallest block which will still be interpreted as a target is cut down to a single ONE. Thus the largest block related to a target has only n - m binary positions. Network 5 has n - m + 3 inputs and a single output 36 energized only if a reduced target block is at the middle inputs of network 5 or if the two target centres of a block correlated with two targets is determined. Output 36 operates two counters 6, 7 which continuously count azimuth and range and pass the result to a computer 8. The embodiment is described in greater detail with reference to Fig. 2 (not shown).

Screws are contained in magazines 12, (Fig. 1),  and the magazines are carried circumferentially by carrier 50. The carrier is freely supported on inclined shaft 15 driven continuously from pulley 16. The screws pass by gravity from the top magazine 12 and fall down rails 32 for delivery to a screw-driver. Whilst one screw remains in the magazine it engages lugs 30 on fixture 29 and prevents rotation of the carrier. As soon as the last screw drops down rails 32, the carrier is driven from the constantlyrotating shaft 15 by means of arm 26, the ball 27 of which engages, as it rotates, with cup 28 of the carrier. When the carrier has rotated to bring the next magazine into alignment with rails 32, the first screw of this magazine will engage lugs 32 and stop the carrier and will then slide down rails 32 as before. Delivery to screwdriver (Fig. 3). The screws which slide down rails 32 are delivered one-byone to screwdriver 11 via pivoted quadrant 35 and fingers 47. Thus the bottom screw falls into a slot in quadrant 35 which is oscillated by means of linkage 44, 41, 42, 39, 40 to swing the screw to the left.
